Hereinafter, the control method of the present invention will be described in detail by taking the washing device as a washing machine as an example; those skilled in the art can understand that although the preferred embodiment is described in conjunction with the situation when the washing device is a washing machine However, it is obvious that the washing equipment may also be other equipment having a washing function, as long as the washing equipment includes a vibration detection switch.

Technical solution 1:

Specifically, in this preferred embodiment, the washing machine includes a cabinet, a washing tub provided in the cabinet, and a tray connected to the cabinet, wherein the tray is provided with vibration detection Switch, the vibration detection switch is used to detect the vibration of the washing machine. During the use of the vibration detection switch, when the washing machine runs smoothly, the vibration detection switch is in a closed state and outputs a high level; while when the washing tub generates vibration and reaches the set maximum vibration amplitude At this time, the vibration detection switch will turn into an off state and output a low level. Those skilled in the art can understand that although the vibration detection switch in the preferred embodiment is provided on the tray of the washing machine; obviously, the vibration detection switch may also be provided in other parts of the washing machine As long as the vibration detection switch can detect the vibration of the washing machine. In addition, the vibration detection switch is preferably a shaking switch or a safety switch of the washing machine; of course, this description is not limitative, and a technician can also select other types of vibration detection switches by themselves.

Further, the washing machine further includes a controller, which can run the control method of the present invention, that is, the controller can obtain the vibration state of the washing machine through the vibration detection switch. As a preferred manner, the controller can obtain the duration of the vibration detection switch in the open state and the closed state by acquiring the duration of the vibration detection switch in the low level and high level, and the control The appliance can also control the operation of the washing machine according to the detection result of the vibration detection switch. Of course, this description is not limitative, the controller may also obtain the duration of the vibration detection switch in the open state and the closed state by other means; for example, the controller may also obtain the The distance between the two contacts of the vibration detection switch is used to obtain the duration of the vibration detection switch in the open state and the closed state. It should be noted that, the controller may also obtain only the duration of the vibration detection switch being in the open state, and not the duration of the vibration detection switch being in the closed state. Those skilled in the art can understand that the present invention does not limit the specific structure and model of the controller, and the controller may be an original controller of the washing machine, or may be a control for performing the present invention. Method and set the controller separately.

First, refer to FIG. 1, which is a flowchart of main steps of the control method of the technical solution 1 of the present invention. As shown in FIG. 1, based on the washing machine described in this preferred embodiment, the control method of the technical solution 1 of the present invention mainly includes the following steps:

S1: Obtain the duration of the vibration detection switch being off;

S2: Selectively stop the washing machine from running the current washing mode according to the duration of the vibration detection switch being in the off state.

Further, during the operation of the washing machine, the controller can control the washing machine to perform step S1, that is, the controller can obtain the duration in which the vibration detection switch is in the off state in real time; what needs to be explained is The present invention does not limit the manner in which the controller obtains the duration of the vibration detection switch being in an off state. A technician can select an acquisition method by using requirements; for example, the controller can obtain the The duration of the vibration detection switch being at a low level to obtain the duration of the vibration detection switch being in the off state, or the controller may also obtain the distance between the two contacts of the vibration detection switch The duration of the vibration detection switch in the off state is acquired, that is, as long as the controller can acquire the duration of the vibration detection switch in the off state. It should be noted that although the trigger state of the vibration detection switch is described as an off state in this application, this is not a limitation of the present invention, and those skilled in the art can also change the trigger state of the vibration detection switch as needed It is described as a closed state, that is, the vibration detection switch is opened in the normal state and closed when the washing machine undergoes large vibrations. This change does not deviate from the basic principles of the present invention, and therefore will fall into the protection of the present invention Within range.

Furthermore, in step S2, the controller can selectively stop the washing machine from running the current washing mode according to the duration of the vibration detection switch being in an off state. Of course, the technician can set The washing machine stops operating in the specific condition of the current washing mode; for example, the controller may compare the duration of the vibration detection switch in the off state with a preset time, or the controller may also compare the vibration The duration of the detection switch in the off state is compared with a preset mapping relationship, so that the controller can selectively stop the washing machine from running the current washing mode according to the duration of the vibration detection switch in the off state . Those skilled in the art can understand that as long as the control method uses the duration of the vibration detection switch in the off state as its basic parameter to control the current operating state of the washing machine, it falls within the protection scope of the present invention.

Next, refer to FIG. 2, which is a flowchart of steps of a preferred embodiment of the control method of the technical solution 1 of the present invention. As shown in FIG. 2, based on the washing machine described in this preferred embodiment, the preferred embodiment of the control method of technical solution 1 of the present invention specifically includes the following steps:

S101: Obtain the duration when the vibration detection switch is at a low level;

S102: Determine whether the duration that the vibration detection switch is at a low level is greater than or equal to a preset time; if yes, perform step S104; if not, perform step S103;

S103: Make the washing machine maintain the current washing mode;

S104: Stop the washing machine from performing the dehydration operation;

S105: Make the washing machine perform the water inlet operation;

S106: Run the pulsator at a preset speed for a first preset time;

S107: Make the pulsator run at the first preset turn-to-stop ratio for the second preset time;

S108: causing the pulsator to run for a third preset time at the second preset turn-to-stop ratio;

S109: Make the washing machine perform the drainage operation;

S110: Make the washing machine continue to perform the dehydration operation.

Further, during the dehydration operation of the washing machine, the controller can control the washing machine to perform step S101, that is, the controller can obtain the duration that the vibration detection switch is at a low level; It is true that although the preferred embodiment obtains the duration of the vibration detection switch being in the off state by acquiring the duration of the vibration detection switch being at a low level, it is obvious that the technician can also obtain the duration by other means The duration of the vibration detection switch being in the off state, as long as the controller can obtain the duration of the vibration detection switch being in the off state. It can be understood that, in the preferred embodiment, when the controller acquires that the vibration detection switch is at a high level, the controller will not adjust the operation of the washing machine; and when the When the controller obtains that the vibration detection switch is at a low level, the controller will collect its duration; of course, the controller may also obtain the time by calculating the time difference between two high levels Duration of vibration detection switch at low level. It should be noted that although the preferred embodiment is described in conjunction with the process of the washing machine performing the dehydration operation as an example, the control method of the present invention can obviously also be used in the process of performing other operations of the washing machine. This change does not deviate from the basic principles of the invention.

Further, in step S102, the controller compares the duration of the vibration detection switch at a low level with the preset time, and determines whether the duration of the vibration detection switch at a low level is greater than Or equal to the preset time. It should be noted that the preset time is preferably 48 milliseconds; of course, technicians can also set the length of the preset time according to actual usage, as long as the preset time can accurately distinguish whether the washing machine is It is enough if there is continuous vibration. Specifically, in step S102, if the controller determines that the duration of the vibration detection switch at the low level is less than the preset time, it means that the washing machine has not produced a continuous vibration phenomenon, for example, The washing machine may only move due to external force; at this time, the washing mode of the washing machine does not need to be adjusted, and step S103 is executed, that is, the controller controls the washing machine to maintain the current washing mode.

Further, in step S102, if the controller determines that the duration of the vibration detection switch at the low level is greater than or equal to the preset time, it indicates that the washing machine has generated a continuous vibration phenomenon; at this time, The controller must adjust the operating condition of the washing machine in order to put the washing machine into a state of stable operation again. Therefore, when the duration of the vibration detection switch in the off state is greater than or equal to the preset time, step S104 is executed, that is, the controller controls the washing machine to stop running the current washing mode, that is, the washing machine The execution of the spin-drying operation is stopped, and the washing machine is operated in the vibration correction mode. In the preferred embodiment, the vibration correction mode includes steps S105 to S109. It should be noted that although the vibration correction mode described in the preferred embodiment includes steps S105 to S109; however, this description is obviously exemplary, that is, the technician can set the vibration correction mode according to the actual situation. The specific operation performed.

Further, in step S105, the controller controls the washing machine to perform a water inlet operation; preferably, the controller controls the washing machine to feed water to a rinsing water level, of course, this is not limitative, and technicians also You can set the water inlet level yourself. Next, in step S106, the controller controls the pulsator of the washing machine to operate at the preset rotation speed for the first preset time, so that the laundry can be fully spread out in the water. It should be noted that, preferably, the preset speed is the washing speed of the pulsator; in addition, when the vibration detection switch is a sway switch, the first preset time is 2 minutes; when the vibration When the detection switch is a safety switch, the first preset time is 1 minute. In step S107, the controller controls the pulsator of the washing machine to operate the second preset time at the first preset turn-down ratio so that the laundry can fully contact the water. It should be noted that, preferably, the first rotation stop ratio is that the pulsator rotates at the washing rotation speed for 0.6 seconds, and then stops for 0.6 seconds; the second preset time is 2 minutes. In step S108, the controller controls the pulsator of the washing machine to operate the third preset time at the second preset turn-stop ratio, so that the laundry is spread as much as possible in the water to be evenly distributed. It should be noted that, preferably, the second rotation stop ratio is that the pulsator rotates at the washing rotation speed for 0.5 seconds, and then stops for 0.5 seconds; the third preset time is 1 minute. A person skilled in the art can understand that the above specific time setting is exemplary, and the technician can set it according to actual use requirements. Finally, in step S109, the controller controls the washing machine to perform a drainage operation so that the washing machine can continue to perform the dehydration operation in step S110.

In addition, based on the above preferred embodiment, the control method further includes: when the number of times the washing machine runs the vibration correction mode reaches a preset number of times, the washing machine can also issue an abnormal reminder to the user. It can be understood that, after the washing machine repeatedly runs the vibration correction mode, if the washing machine still generates continuous vibration, it means that the laundry correction mode alone has been unable to wind the laundry in the washing machine. Separate; therefore, the washing machine needs to issue an abnormal reminder to the user, and even prompts the user to manually unwind the entangled clothes, so that the user can accurately and efficiently solve the problem, thereby ensuring the safe operation of the washing machine to the greatest extent. A person skilled in the art can understand that the technician can set the specific value of the preset number of times according to actual usage; preferably, the preset number of times is 4 times.

Technical solution 2:

Specifically, in the preferred embodiment, the washing machine includes a cabinet, a washing tub provided in the cabinet, and a tray connected to the cabinet, wherein a swing switch is provided on the tray And a safety switch, the shaking switch and the safety switch are used to detect the vibration of the washing machine. During the use of the shaking switch and the safety switch, when the washing machine runs smoothly, the shaking switch and the safety switch are both in a closed state and output a high level; and when the washing tub vibrates When the phenomenon reaches the maximum vibration amplitude set by each, both the sway switch and the safety switch may change to an off state and output a low level. A person skilled in the art can understand that although the rocking switch and the safety switch described in this preferred embodiment are provided on the tray base of the washing machine; however, the rocking switch and the safety switch can obviously also be provided In other positions of the washing machine, as long as the shaking switch and the safety switch can detect the vibration of the washing machine. In addition, although the first vibration detection switch described in this preferred embodiment is a sway switch, and the second vibration detection switch is a safety switch; however, it is obvious that the technician can also select other types of vibration detection switches according to actual use requirements.

Next, in step S105, the controller controls the pulsator of the washing machine to operate the first preset duration at the preset rotation speed, so that the laundry can be fully spread out in the water. It should be noted that, preferably, the preset speed is the washing speed of the pulsator; in addition, when the washing machine runs the first vibration correction mode, the first preset duration is 2 minutes; when the When the washing machine runs the second vibration correction mode, the first preset duration is 1 minute. In step S106, the controller controls the pulsator of the washing machine to operate the second preset period of time at the first preset rotation stop ratio so that the laundry can fully contact with water. It should be noted that, preferably, the first rotation stop ratio is that the pulsator rotates at the washing rotation speed for 0.6 seconds, and then stops for 0.6 seconds; in the first vibration correction mode and the second vibration correction mode The second preset duration is preferably 2 minutes. In step S107, the controller controls the pulsator of the washing machine to operate the third preset time longer than the second preset spin-stop ratio, so that the laundry is spread as much as possible in the water to be evenly distributed. It should be noted that, preferably, the second rotation stop ratio is that the pulsator rotates at the washing rotation speed for 0.5 seconds, and then stops for 0.5 seconds; in the first vibration correction mode and the second vibration correction mode The third preset duration is preferably 1 minute. A person skilled in the art can understand that the setting of the above specific duration is exemplary, and the technician can set it according to actual use requirements. Finally, in step S108, the controller controls the washing machine to perform a drainage operation so that the washing machine can continue to perform the dehydration operation in step S109.
